Coming from someone who mains a Monk (and also FDK) and has raided and M+'d as WW a lot, I must say, the Demonic build (3 3 3 3 3 1 3, I went Master of the Glaive over Demon Reborn after the meta added time nerf) is super fun.
Especially coming from WW where AoEing is just NOT FUN at all. Having to tab target in a game where tab targeting is AIDS is just super frustrating. Also having FoF miss half the targets because it only has like a 3 inch reach is also NOT FUN. I love that Eye Beam has like a 20 yard range and I can snipe all the mobs.
I'm still undecided on either Bloodlet or First Blood. I like the FB makes BD cost less Fury (so I can CS more while in meta form) and do more damage on 1 target, but the DoT on GT is too good for M+ where I can DoT multiple targets up and then go to town with Eye Beam.
